                                 CERTIFICATIONS

I, Gary C. Evans, certify that:

         1.    I have reviewed this annual report on Form 10-K of Magnum Hunter
               Resources, Inc.;

         2.    Based on my knowledge, this annual report does not contain any
               untrue statement of material fact or omit to state a material
               fact necessary to make the statements made, in light of the
               circumstances under which such statements were made, not
               misleading with respect to the period covered by this annual
               report;

         3.    Based on my knowledge, the financial statements, and other
               financial information included in this annual report, fairly
               present in all material respects the financial condition, results
               of operations and cash flows of the registrant as of, and for,
               the periods presented in this annual report;

         4.    The registrant's other certifying officers and I are responsible
               for establishing and maintaining disclosure controls and
               procedures (as defined in Exchange Act Rules 13a-14 and 15d-14)
               for the registrant and we have:

                      a)      designed such disclosure controls and procedures
                              to ensure that material information relating to
                              the registrant, including its consolidated
                              subsidiaries, is made known to us by others within
                              those entities, particularly during the period in
                              which this annual report is being prepared;

                      b)      evaluated the effectiveness of the registrants'
                              disclosure controls and procedures as of a date
                              within 90 days prior to filing date of this annual
                              report (the "Evaluation Date"); and

                      c)      presented in this annual report our conclusions
                              about the effectiveness of the disclosure controls
                              and procedures based on our evaluation as of the
                              Evaluation Date;

         5.    The registrant's other certifying officers and I have disclosed,
               based on our most recent evaluation, to the registrant's auditors
               and the audit committee of registrant's board of directors (or
               persons performing the equivalent function):

                      a)      all significant deficiencies in the design or
                              operation of internal controls which could
                              adversely affect the registrant's ability to
                              record, process, summarize and report financial
                              data and have identified for the registrant's
                              auditors any material weaknesses in internal
                              controls; and

<PAGE>
                      b)      any fraud, whether or not material, that involves
                              management or other employees who have a
                              significant role in the registrant's internal
                              controls; and

         6.    The registrant's other certifying officers and I have indicated
               in this annual report whether or not there were significant
               changes in internal controls or in other factors that could
               significantly affect internal controls subsequent to the date of
               our most recent evaluation, including any corrective actions with
               regard to significant deficiencies and material weaknesses.
